🔬 Morphology

Cap

Dark honey fungus

The cap of dark honey fungus is 4 to 10, occasionally up to 15 centimeters across. When young it is hemispherical or convex-bell-shaped; with age it opens up to flat with a small bump. The surface is covered with conspicuous dark — brown to blackish — flattened scales, especially dense in the center. The color is yellowish brown, honey brown or dark reddish, darker than honey fungus. The dark scaly cap is a characteristic feature of the species.

Ringless honey fungus

The cap of ringless honey fungus is 3 to 8 centimeters across. When young it is convex-bell-shaped; with age it opens up to flat, sometimes with a small bump. The surface is covered with small, flattened scales, especially in the center. The color is honey yellow, ocher-reddish or yellowish brown, darker in the center. The honey color and scaliness make it resemble honey fungus, but the margin is often paler.

Hymenophore

Dark honey fungus

The hymenophore is gilled. The gills are whitish or cream, developing yellowish-brown spots with age; they are attached to the stem or run slightly down it. The spore print is white. Pale gills that turn brown with age, together with the ring on the stem, help you recognize dark honey fungus.

Ringless honey fungus

The hymenophore is gilled. The gills are whitish or cream, developing pinkish-brown spots with age; they are attached to the stem or run slightly down it. The spore print is white. Pale gills that turn brown with age, together with the absence of a ring on the stem, help you recognize this species.

Stem

Dark honey fungus

The stem is cylindrical, 6 to 15 centimeters tall, fairly firm and fibrous, often with a thickened base. Its defining feature is a well-developed, sturdy, whitish ring in the upper part, often with brown scales along the edge. Above the ring the stem is pale; below it, reddish brown and fibrous. Several stems often grow fused together in a cluster. There is no volva.

Ringless honey fungus

The stem is cylindrical, tapering toward the base, 5 to 12 centimeters tall, fibrous and tough. Its defining feature is the complete absence of the ring that honey fungus has; the stem is smooth along its entire length. It is yellowish at the top and reddish brown lower down, and several stems often grow fused together in a cluster at the base. There is no volva.

Flesh

Dark honey fungus

The flesh is whitish, fairly firm in the cap and fibrous and tough in the stem. It barely changes color when cut. The taste is mild and pleasant, but because the raw mushroom tends to cause stomach upset, it must always be boiled thoroughly. Young caps are chosen for the table, while old fibrous stems are usually discarded.

Ringless honey fungus

The flesh is white or cream, fairly thin in the cap and fibrous and tough in the stem. It barely changes color when cut. The taste is mild and pleasant, with no bitterness, but because the raw mushroom tends to cause digestive upset, it must always be boiled thoroughly before eating. Young caps are chosen for the table.

Smell

Dark honey fungus

The smell is faint, pleasant and mushroomy, with no sharp notes. Aroma is not a defining feature, so for identification rely on the dark scaly cap, the ring on the stem, growth in dense clusters on conifer wood and the autumn season.

Ringless honey fungus

The smell is faint, pleasant and mushroomy, with no sharp notes. Aroma is not a defining feature, so for identification rely on the honey-colored scaly cap, the absence of a ring on the stem, growth in dense clusters on the roots of broadleaf trees and the late-summer-to-autumn season.
